Flying Images WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Flying Images: Optimize and Lazy Load Images for Faster Page Speed plugin for WordPress, affecting all versions through 2.4.14.

These scripts execute when a user accesses the compromised page. This issue is present in multi-site installations where unfiltered_html has been disabled.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the affected page.

Remediation

Users can update to version 2.4.15 or a newer patched version to address this vulnerability.
